Dealing with Lag

[mcarrara]

I could not get multiple cameras to work for my football game Friday. I don't think it is a Mogulus issue, but a bandwidth issue. I was near the end of the 100m distance between switches for Ethernet, and I doubt my connections would certify as Cat 5e. We have a T1 line and our streams were about 600 mbs. we could not switch between cameras. We could have reduced quality and that may have worked, but we decided to keep quality and go with only one camera.

Now if someone has a spare $6,000 laying around I would use it to buy a NewTek Tricaster and do live switching on site and send only one stream to Mogulus.

We have been capturing HS Sports for many years. Getting the stream to run over wireless is what we are really good at. Regardless of what a Techno Nerd says here is what we know.
1) 802.11(abgn) allows all devices to say hello. This disrupts the continuity.
-a) If you encrypt it to dissallow others to connect - Kiss Video/Audio continuity good bye
-b) For Captive portal Technology you need the IP's of the mogulus backend. Not Available.
2) Cost Effectiveness is my delimma - $150,000 for a four Camera System is not affordable.
3) We have the equipment ready for the WiMax as a back haul but no one wants to wait.
4) So far qik.com has made it far easier to do the live but it is man hour intensive.
-a) We have students for the man hours, now the training costs are being researched.
-b) Moving around with laptops USB Streaming with Sony Digital8 Camcorders is a problem
-c) Working on Mikrotik using nStream 108 mbps to accomplish the High Speed network.
This is just a short version of what we have.
Our current setup is a single Sprint/Verizon EVDO WAN for our MobileNet (EVDO to 802.11g Router) We built a Tripod for Outdoor use self powered and we are working on a Wireless USB stream prototype, to allow moving down the sidelines without the laptop in tow.
Currently our setup equipment costs about $1500.00 not including the Laptop and Camcorder. We are also looking into using a cheap van with batteries, 30' extendable pole and aggregating 4 EVDO WAN's to compensate for the lack of a data line. As well as Point to Point equipment to use when a data connection is available. The cost of this so far is only at $25,000.00.
So my interest in your topic is this...
Would 4 USB cameras show up on a single PC so that you can switch properly. I ask this because it would be far easier for me to make USB work wirelessly than to make four computers connect to a network and avoid the latency and bandwidth issues.
The other question is if there are any cameras that are network capable with stream capabilities. As, bandwidth can be increased by using two radios per node. Easier to power two radios and network camera than to power Camera, Laptop and Node.
Sorry for the rambling but I look at every option and perfect the best. Money is the only challenge here. We are seeing budgets for this being about $5,000.00 for the Year to include everything. So far we are at about $7,500 to get it done, which considering we have no cost estimates on Mogulus Pro, means $2,000.00 in equipment is what we are shooting for.

You raise some very interesting points here.

What do you mean by:

4) So far qik.com has made it far easier to do the live but it is man hour intensive?

[WiFiTech]

Using the qik.com with mogulus meant we had to coordinate the use. We ran a recorded feed of nothing, then cued each person to stream live over it, then would cue them the next to start and have the previous stop in 3 seconds. We finally were able to get a decent style of stream but it took 3 people with qik.com on thier phones, two way radios and then one person manning studio and one more calling the cues.
We are now searching for a less man hour intensive one.
I was working on 4 intel Atom PC's in weather boxes with WiFi and USB PTZ cameras with VNC to operate them to record Youth Sports, but the economy has me on hold. I will work on it again once I have an extra $2000.00 dollars. If someone wants to loan the cash for the hardware or pick up what I need, I would be happy to configure it and send it back.
I had it working with 4 desktops and 4 webcams but had to give all my friends thier stuff back before I found mogulus. I have been doing live web streaming from a vehicle for about two years. We just couldn't sell it to the Police Departments without a grant and I don't have the $25k it would take to get one written.

Hi, my name is Justin Wilson, I am the owner and creator of This and That Radio Networks. I have found that if you increase the video quality, it helps the lag. If you are using a webcam, then you will always have this problem. But while I was on your channel, your reply of a rally looked really good. It had no lag. Very good sound, and picture. Hope this helps. Also please check out my channel sometime at:

We were connected on a Internet acces 1 km away. This internet acces had 256Kb/s in upload.

The wireless bridge was able to transmit all the bandwith (256Kb/s) without loss.

We used the flash encoder directly. We almost had no lag (but the quality was bad due to the 160Kb stream...).

how to solve the multi camera:
At present, we don't know how to mix live several network streams localy, to send only one stream out of the track to mogulus. But it seams that the microsoft Expression Encoder is able to mix live several sources. What i dont know is if it's able to mix network live streams, and if it's able to reencode with flash codec... I dont have it and haven't tested it... If somebody has tested it, give us your feedback... Sure it woul'd be great to have multi camera live...

Bye!!

Hi

Have you tried Vidblaster Pro this works like studio video switcher, you can have up to 4 camera, VCR etc and videos on your PC stream to Mogulus as a single source and mix all your videos realtime.

Let me know if you need the software please.

Hi,

Yes, I'm interested in this Software... Where have found it?
http://vidblaster.com ?

It seems to be great!! Does it run correctly? Does it produce flash stream?

Bye!

I have a question, are you all using the free service or the premium channels? The difference being from 500kbps to like 1.7 mbps. And if so does it make that big of a difference seeing all the tech problems everyone is having.

[autocross]

I 'll stop using Livestream because they introduce un 50 concurent users limitation.

I'll evaluate Justin.tv and ustream.tv which are similar services.

In the case it doesn't run correctly, I 'll continue to use my actual dedicated server with 100mb bandwith at 30€/month...

I uses VLC with a WMV stream to broadcast, but I 'll try soon a Red5 server with a flash stream.

Bye!
